Fordman- I'll bet your smell is in the tune. My crankcase is vented to atmoshpere, and I was having the very same smell with my car(oh, did I mention it was drinking gas, gas was polluting the oil, and it idled like it had a huge cam in it). I recently bought a tweecer, and began with the maf tranfer. I had to lean the curve almost by half to get the computer to take over. To make a long story short, now I have the maf correct, my computer is functioning like it should, the smell is gone, stock idle and drivability are back and I just checked my mpg. 19 with the egr system off. You can't beat that.
If I'm not mistaken you get your car tuned by a pro. I'll bet if you aren't running an fmu your car is very rich in normal driving situations.
Just a thought.
